Muxy Extensions Developer Kit

Building Twitch Extensions is hard. Muxy makes it easier.

As one of the first developers to make an Extension, we spent months developing a powerful enough backend to power all of the apps we wanted to bring to Twitch. We're providing our backend and libraries so you don't need extensive domain knowledge to build an Overlay App or Twitch Extension.

Get started

Backend

The missing piece of Twitch Extension Development. Run at Twitch scale without worring about servers. We handle the entire backend so you can focus on creating interactive experiences for Twitch viewers.

Dev environment

The Muxy Twitch Extensions dev environment mimics the live Twitch environment. It handles user authentication, analytics, context switching, and environment detection. We even provide live code updating so you don't have to refresh!

Third Party Apps

Already have an existing game or application? Let broadcasters sync data with their Twitch account with a secure PIN, and simple POST request.

Muxy Overlay App Rig

Muxy Extension Rig

The Rig simulates the Twitch environment that Twitch Extensions run in. Combined with the Muxy SDK it allows Twitch Extensions to
safely be sandboxed away from production data and any hiccups that can happen on Twitch's site. When running in the rig
the Muxy SDK also provides a pubsub system that works exactly like the production one on Twitch.
